Understanding Moon Phases: A Beginner's Guide for 2026

The moon's phases are a captivating aspect of our night sky, offering a rhythmic cycle that has intrigued humanity for centuries. In 2026, this cycle presents numerous opportunities for observers in the United States to engage with lunar phenomena.

What Are the Moon's Phases?

The moon undergoes a continuous cycle of phases, transitioning from new moon to full moon and back over approximately 29.5 days. This progression is due to the changing angles between the Earth, moon, and sun, which affect the portion of the moon's surface illuminated by sunlight. The primary phases include:

  • New Moon: The moon is between the Earth and the sun, making it invisible from Earth.
  • First Quarter: Half of the moon's surface is illuminated, appearing as a half-circle.
  • Full Moon: The entire face of the moon is illuminated, appearing as a complete circle.
  • Last Quarter: Similar to the first quarter but on the opposite side.
